Abstract (en)
A compressed data table is formed from an uncompressed data table by defining a code description bit structure having a code type and a run length of data items. The code type may be configured to identify byte-length data items, word-length data items and/or one or more user-specified data items. Each run of one or more byte-length, word-length or user-specified data items in the uncompressed data table is represented in the compressed data table with a code description bit structure having an appropriately configured code type and having its run length equal to the number of byte-length, word-length or user-specified data items in the run of one or more byte-length or word-length data items, and in the case of byte-length and word-length data items each code description bit structure is followed in the compressed data table by the one or more byte-length or word-length data items.
